To all whom it may concern. I Be it known that I, SILAS M. FORD, a citi- -zen of the United States, and a resident. of V St. Paul, in the county of Ramsey and State have invented certain new and useful Im roveinents in Machines for Making Lathoard. of which the following is a specification.

ThlS invention relates particularly to a machine for making lath-board wherein the lath-board, preferably of water-proofed fibrous material, is crimped into a corruof Minnesota,

gated or dove-tailed shape, and means are gether and maintain them in this relation as gations tures of construction [is-taken from t e progress through the .machine. other object of my invention is to prooscillator-y means for pressing corruorplates formed in the machine into-more intimate relations with each other and maintainllthem in this relation as they pass through the machine.

Another objbctof my invention is to pro-v vide an bscillatory member that will strike alternately the two edges of plaits formed by the machine oscillation of the on alternate cycles of the member. .With these and incidental ob ects in view, the invention consists otcertain novel -feaarts-the essential elements-of which are ereinatter described withre; ftjence-to the drawings which accompany-ail form a part ofthis specification.

water-.pnoofed pager or jwhatever-maing the lath-board, Fig.1 in, which {it paper and -force these and combination of .thleading rollers?! 'fso spaced, slats will ides used for The paper 3 passes through the guides 24 of the crimping ro ls 5 and 6, which are geared together and driven by-any suitable means, and cleats 7 crimp the paper into a iorrugated shape, as plainly shownin preferably use guides for the removal of the paper from the corrugating rolls as described in my copending applicationheretofore referred to, and as their action is similar they will not be further described in this specification.

I utilize a pair of rocker bars 33", Fig. 1, driven by connecting ions 35, which in turn are driven-by gears carried by the rolls 5 and 6 to form the rec-- tangular corrugations'into dovetailed corrugations.

,The resultant oscillator thro'ugh'the gearing, so t at when the face motion is timed 36 travels in an anti-clockwisedirection, it

will strike points 37 of the Y and press it downwardly; while the-face. 38,- also traveling in an .anti-clockwise direction,,will strike points-39 of the corrugated portions of the paper upwardly. I I

-On the return stroke of the oscillatory moe tion the surface 36 while traveling in .a clockwise direction, and the face 38 will stri e points 41, also While traveling in. a. clock .is'e direction, so that by the action of the rockenarms, the corrugated shape is forced. into the dove-tailed shape, shownat 42. I I prefer to use with .thismethod a pair of s ueeze rolls 43, abso'ute'l essential.

Wi'thQt is construction I utilize a pai'ro'f.

I having slots 45 thereon. and the rolls so geared thatthese' V register with the spaces between the surfaces fifofthe dove-tailed paper. These slats have slots to receive and support the reinforcing wires 2Q and tlifeyare threaded throughthe webs'lO of the corrua" gated lath-board at this point to stiiien'antl reinforce the lath-board.

and. slotted Band 4 suit-ably mounted guides 47, Figs. on,'th e frame of "the mac me.

corrugated paper although they-are" not;

Will strike points 40,

- For guiding;i the wires 26-l' provide a se-. l'leS'Of pivote onto the wires, and as the dovetailed paper with the Wires therein reach the guides and. force them into the position shown on tie standard 50, the paper with the wires threaded through rides easily over the, pivoted guides and. they disappear below the surface of the lath like faces of the paper,

and the slots are thereby disengaged with the wires which at this time are firmly re inforced by the paper through. which the wires have been forced.

With the construction shown in, Figs- 1, '52-, 3 and 4, the guide wires would pass through the rolls and slats used in the forming of the dove-tailed lath-board, and the thread ing means in the same manner as airs-any de scribed in my copending application aforsaid.

With the construction as shown, thtiguides 4 run entirely through the forn lng and narrowed socia threading portion of the maciine, and I prefer to have the uides narrowedat the mute in the forming machine where the orrning of the lath-hoard is changed from a corru ated to adoiretailed shape, so that while t e lathboard fits the guides closely in itscorrugated shape, it will also fit the 7 guides closely in its dove-tailed shape. 7

WVhile I have describe i invention and illustrated it in one particu ar design, I do not wish it understood-that 1 limit myself to this construction, as is evident that the application of my hire on may hevaricd in many ways within tlije scope of the followinIg claims: i
